There is uncertain result with regard to the use of inhalation or instillation steroids to prevent bronchopulmonary dysplasia in preterm infants. This meta-analysis was designed to evaluate the efficacy and safety of early airway administration (within 2 days after birth) of corticosteroids and pulmonary surfactant (PS) for preventing bronchopulmonary dysplasia (BPD) in premature infants with neonatal respiratory distress syndrome (NRDS). The related studies were retrieved in PubMed, EMBASE, the Cochrane Library, Clinical Trial, CNKI, Wanfang and VIP Database from inception to August 2018. Two reviewers independently screened the studies to ensure that all patients with diagnosis of NRDS were enrolled to studies within 1 day after birth, assessed the quality of included studies by GRADEpro system and extracted the data for review. The meta-analysis was performed by RevMan 5.2 software. A subgroup analysis about inhaled corticosteroid (ICS) delivery method was made between ICS inhalation subgroup [inhalation of ICS by nebulizer or metered dose inhaler (MDI)] and ICS intratracheal instillation subgroup (PS used as a vehicle). Eight randomized controlled trials were enrolled in the meta-analysis, 5 trials of which stated the randomized method, grouping and blinded method, and the follow-up procedures were reported. GRADEpro system showed high quality of 4 trials (5 articles), and the rest 4 trials had moderate quality. Meta-analysis showed that the incidence of BPD was decreased in ICS group, the relative risk (RR) was 0.56 (95% CI: 0.42-0.76), and similar trends were found in ICS inhalation subgroup and ICS intratracheal instillation subgroup, with the corresponding RR being 0.58 (95% CI: 0.41-0.82) and 0.47 (95% CI: 0.24-0.95) respectively. ICS could also significantly reduce the mortality risk as compared with placebo control group (RR: 0.67; 95% CI: 0.45-0.99), with RR of ICS inhalation subgroup and ICS intratracheal instillation subgroup being 0.81 (95% CI: 0.34-1.94) and 0.64 (95% CI: 0.41-0.99) respectively. Moreover, the percentage of infants using PS more than one time was lower in ICS group than in the placebo control group, with the RR and 95% CI being 0.55 (95% CI: 0.45-0.67), and that in ICS intratracheal instillation subgroup lower than in ICS inhalation subgroup (RR: 0.56; 95% CI: 0.45-0.69, and RR: 0.35; 95% CI: 0.08-1.52 respectively). There was no significant difference in the incidence of infection or retinopathy of prematurity and neuro-motor system impairment between ICS group and placebo control group, with the corresponding RR being 0.95 (95% CI: 0.59-1.52), 0.92 (95% CI: 0.62-1.38) and 1.13 (95% CI: 0.92-1.39), respectively. It was concluded that early administration of ICS and PS is an effective and safe option for preterm infants with NRDS in preventing BPD and reducing mortality, decreasing the additional PS usage, especially for the ICS intratracheal instillation subgroup. Furthermore, the appropriate dose and duration of ICS, combined use of inhalation or instillation of ICS with PS and ...
Background: Cutis laxa is a connective tissue disease characterized by loose, wrinkled, and redundant skin. It is either inherited or acquired. In most cases, acquired cutis laxa is associated with neoplasms, drugs, and autoimmune diseases. We present a rare case of acquired cutis laxa following a recurrent urticaria-like eruption in the absence of an autoimmune disease, neoplasm, drugs and or syndrome. Case presentation:We report a case of a 45-year-old Chinese lady with a 1-year history of widespread pruritic urticarial eruption and a 6-month history of progressive skin wrinkling. On examination, the patient appeared older than her actual age, with apparent wrinkling on the mid-torso with generalized smooth, erythematous macules and wheals. A family history of similar conditions was absent. Biopsy revealed hypersensitivity and atrophy. Following the Food and Drug Administration (FDA) guidelines, we administered antihistamines, which relieved the itching, but her hyperpigmentation and cutis laxa never improved. Conclusion:Our case shows that the decrease of elastic fibers may be associated with the infiltration of inflammatory cells in the dermis. This supports the hypothesis that chemical mediators may play a major role in the destruction of elastic fibers, thus causing cutis laxa. In addition, we advise practitioners to take a complete clinical and family history to determine if the condition is inherited or acquired.

Diazepam 10 and 20 mg, lorazepam 2.5 and 5.0 mg, flunitrazepam 1 and 2 mg, and a placebo, were compared in a randomized double-blind controlled trial as oral premedication for 210 patients undergoing minor gynaecological surgery. Flunitrazepam 1 mg and lorazepam 2.5 mg were superior to placebo (P less than 0.001 and P less than 0.05 respectively) in relieving patient anxiety when assessed by a trained observer 60 min after premedication. Flunitrazepam 1 mg also produced more drowsiness (P less than 0.01) than the placebo. Comparisons of other low-dose benzodiazepine groups with the placebo, and of the large dose with the small dose of each drug revealed no significant changes in anxiolysis or drowsiness. Dizziness and prolonged drowsiness were not apparent with low-dose flunitrazepam. The data suggests that flunitrazepam 1 mg offers advantages over placebo, diazepam 10 mg and lorazepam 2.5 mg for routine oral premedication in minor gynaecological surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
